PlAZOMIAS VARICOLOB, Sp. nO\ . 



Long-. 6-7, lat. 2|-3 mm. 



Head slightly convex, rugosely plicate and with a nariow 

 central stria, the sculpturing more or less hidden by dense 

 scaling ; eyes lateral, almost circular, liostmm about as long as 

 head, subquadrate and not narrowed apically ; upper surface 

 plane, subrugose, plicate in the basal half, usually with a shallow 

 depression in the middle and with a central stria continuous with 

 that on the head, with dense scaling and short erect pale setse. 

 Antennce piceou.s, with grey pubescence ; scape abruptly clavate, 

 reaching middle of eyes ; funicle with first joint much longer and 

 thicker than the rest, second as broad as third and only a little 

 longer. Prothorax as long as broad, truncate at base, apical 

 margin scarcely narrowed and slightly rounded doi-sally, sides 

 moderately rounded, broadest at middle ; tipper surface convex, 

 but subdepressed in the middle, closely set with round flattened 

 tubercles except along the median part of the anterior margin, 

 and with a distinct narrow central furrow which reaches neither 

 base nor apex ; colour black, with dense scaling which is fuscous 

 dorsally with two paler bands of either grey, light brown or dull 

 gold ; the underparts entirely of the same colour as the discal 

 bands. Elytra ovate, the basal margin a little broader than the 

 prothorax, truncate and narrowly elevated ; sides slightly rounded, 

 broadest about middle ; upper surface somewhat convex and 

 gradiTally declivous behind, with distinct deeply punctured stride ; 

 the intervals narrow, convex, finely aciculate and with regular 

 rows of long erect distant pale setje ; coloui' black, covered with 

 dense scaling of very variable colouring, being either uniform 

 pale sandy grey, dark grey or dull goldeu, or grey with darker 

 mottling, or dark brown with a broad lateral stripe of brownish

 crenulate internally, especially the anterior pair. 



Mashonaland : Salisbury {G. A. K. M.). 



Types, 6 in the British Museum, 5 in the Oxford Museum. 



The long erect setse on the elyti'a will render this species easily 

 recognisable. 



PlAZOMIAS DECEPTOR, sp. nOV. 



Long. 54-6, lat. 2f-2i mm. 



Head broad, slightly convex, coriaceous, not plicate, and with a 

 narrow central stria. Rostrum as long as head, subquadrate, 

 scarcely narrowed apically ; upper surface plane, coriaceous, with 

 a very short central furrow in the basal half and close to it on 

 each side a much longer furrow which curves strongly backwards 

 towards the inner margin of the eye ; the sculpturing normally 

 hidden by dense scaling. Antennce quite similar to those of 

 P. varicolor. Prothorax as long as broad, basal margin faintly 

 sinuate, apical margin a little narrower and slightly lobate ; sides 

 moderately rounded, broadest at middle ; upper surface somewhat 

 convex, rugosely coriaceous, but smoother near apical margin and
